The impact of addition of olive oil on thermal degradation of refined rapeseed oil
PublicationFats are an important component of the everyday diet and have a significant impact on the proper functioning of human organism. However, during the process of frying chemical transformations take place in the oil; hence fats characterised by high oxidative stability should be given preference. The aim of this work was to determine the quality of rapeseed oil, blended oil, and refined olive oil, all sourced from the domestic market....

Wzajemna zależność procesów kurczenia i suburbanizacji na przykładzie miast niemieckich
PublicationProces kurczenia struktur miejskich związany jest ze zmianami kulturowymi. W Niemczech po zjednoczeniu proces ten przebiega w obu częściach Federaji odmiennie. W landach wschodnich pustoszeją historycznie ukszatłtowane kwartały miejskie i wielkie osiedla, a w landach zachodnich kurczenie dotyka glównie gminy wiejskie. W obu przypadkach odpływająca z miast ludność zasila strefę podmiejską wzmagając tempo procesu suburbanizacji....
